6 Hillgrove, founded by Richard Hillgrove, won the PR account for Corré and Westwood’s Talk Fracking campaign in January. Talk Fracking has 100 signatures from celebrities including Sir Paul McCartney, Yoko Ono, Lily Cole and Russell Brand.
Corré said: "6 Hillgrove PR has an approach that cuts through the crap and actually works. Conventional PR is not good value for money any more.
"6 Hillgrove has the ability to break the mould, using a radical approach that delivers where others fail. I have achieved more with 6 Hillgrove in the first months than I have in years with other PR companies."
Corré co-founded British lingerie retailer Agent Provocateur in 1994. He has a majority stakeholding in theatrical make-up company Illamasqua and owns menswear store A Child of the Jago, which opened its second shop in Soho in October 2014.
